Professional MPPT charge controller with maximum conversion efficiency up to 97.6% and intelligent three-stage charging.
The XTRA-N G3 solar charge controller represents an advanced solution for charging and battery management in solar systems. Thanks to innovative MPPT technology with ultra-fast tracking, it achieves a minimum efficiency of 99.5% in maximum power point tracking. The controller automatically recognizes 12/24 V system voltage and offers a maximum charging current of 30 A.
The device supports adaptive three-stage charging with lithium battery activation capability and automatic temperature compensation for lead-acid batteries. The constant voltage output function enables direct load power supply from solar panels even without a connected battery. With IP33 protection and an operating range of -25 to +45 °C, it is suitable for demanding outdoor applications including RVs, residential systems, and field monitoring.
Advanced Charging Modes
The controller offers adaptive three-stage charging with automatic temperature compensation for lead-acid batteries (default -3 mV/°C). Stable lithium battery activation function ensures safe charging of modern LiFePO4 batteries.
Comprehensive System Protection
The device is equipped with complete electronic protection including overload protection, output short circuit protection, overheating protection, and reverse polarity protection. It operates with charging current and discharge current limiting according to specifications.
Remote Monitoring and Communication
Through the RS-485 interface (5 VDC/200 mA, 9600 b/s speed), optional 4G or Wi-Fi modules can be connected for remote parameter reading and settings adjustment via app. The LCD display provides instant system status overview with adjustable backlight (default 60 s, range 0–999 s).
